Rsync service installation (two)

Rsync push-pull backup

Requirements:
Configuring rsync service data can be achieved by all equipment and prepare
the environment to prepare:
server
CentOS7.6 backup01
eth0: 10.0.0.41/24 eth1: 172.16.1.41/24
client
CentOS7.6 web01
eth0: 10.0.0.7/24 eth1: 172.16.1.7/24

Realization of ideas
install Rsync service> configuration server and client configuration file> backup needs

Step one:
server

Installation Rsync service

[root@backup ~]# yum install -y rsync

Installed:
  rsync.x86_64 0:3.1.2-6.el7_6.1                                                                                      

Complete!
[root@backup ~]#

Step two:
Delete the contents of the original configuration file, modify the following

[root@backup ~]# vim /etc/rsyncd.conf     #rsync的配置文件
uid = rsync                               #运行进程的用户
gid = rsync                               #运行进程的用户组
port = 873                                #监听端口
fake super = yes                          #无需让rsync以root身份运行，允许接收文件的完整属性 
use chroot = no                           #禁锢推送的数据至某个目录，不允许跳出该目录
max connections = 200                     #最大连接数
timeout = 600                             #超时时间
ignore errors                             #忽略错误信息
read only = false                         #对备份的数据设置可读写
list = false                                #不允许查看模块信息
auth users = rsync_backup                   #定义的虚拟用户，作为连接认证用户
secrets file = /etc/rsync.passwd            #定义rsync服务用户连接认证密码文件路径
log file = /var/log/rsyncd.log              #rsync的日志信息
#####################################
[wesley]                                    #模块名称
comment = welcome to oldboyedu backup!      #模块注释信息
path = /backup                              #定义接收备份数据目录
~               

Step three:
Create System User rsync and does not allow users to log on to create a home directory

[root@backup ~]# id rsync
id: rsync: no such user
[root@backup ~]# useradd rsync -s /sbin/nologin -M
[root@backup ~]# tail -1 /etc/passwd
rsync:x:1000:1000::/home/rsync:/sbin/nologin
[root@backup ~]#

Step Four:
Create a backup directory, and authorized users as rsync owner

[root@backup ~]# mkdir /backup
[root@backup ~]# chown -R rsync.rsync /backup/

: Step Five
(use for client connection) rsync create a virtual user's user profile password

[root@backup ~]# echo "rsync_backup" >/etc/rsync.passwd
[root@backup ~]# chmod 600 /etc/rsync.passwd
[root@backup ~]#

Step Six:
After the configuration file is modified, restart the service and add the boot from Kai

[root@backup ~]# systemctl start rsyncd
[root@backup ~]# systemctl enable rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.
[root@backup ~]#

Step 7:
Check rsync port

[root@backup ~]# netstat -lntup|grep rsync
tcp        0      0 0.0.0.0:873             0.0.0.0:*               LISTEN      16635/rsync         
tcp6       0      0 :::873                  :::*                    LISTEN      16635/rsync         
[root@backup ~]#

Above server configuration

Began to configure the client
Step one:
install Rsync service

[root@web01 ~]# yum install -y rsync
Installed:
  rsync.x86_64 0:3.1.2-6.el7_6.1                                                                                      
Complete!
[root@web01 ~]#

Step two:
Create a virtual user's password permissions and authorization for the security permissions of 600

[root@web01 ~]# echo "123456" >/etc/rsync.passwd
[root@web01 ~]# chmod 600 /etc/rsync.passwd
[root@web01 ~]#

Client Configuration End

Test
Client Push everything under the etc directory to Rsync server

[root@web01 ~]# rsync -avz /etc/ [email protected]::wesley

Test Two
data service client pull Rsync wesley end module to a local directory data

[root@web01 cs]# rsync -avz [email protected]::wesley ./ --password-file=/etc/rsync.passwd

Local transmission
backup etc directory to the directory ./

[root@web01 cs]# rsync -avz /etc/ ./

Create a new file to achieve incremental backup

[root@web01 cs]# touch /etc/123.txt
[root@web01 cs]# rsync -avz /etc/ ./
sending incremental file list
./
123.txt
sent 43,989 bytes  received 641 bytes  89,260.00 bytes/sec
total size is 27,224,604  speedup is 610.01
[root@web01 cs]#

Remote transmission
pull remote file

[root@web01 cs]# rsync -avz [email protected]:/etc/passwd ./
[email protected]'s password:
receiving incremental file list
passwd
sent 43 bytes  received 448 bytes  196.40 bytes/sec
total size is 843  speedup is 1.72
[root@web01 cs]#

Pull the ball all the files in the remote directory

[root@web01 cs]# rsync -avz [email protected]:/etc/ ./
yum/vars/infra
sent 34,535 bytes  received 10,324,421 bytes  1,381,194.13 bytes/sec
total size is 27,224,646  speedup is 2.63

Pull remote directory and all files in a directory

[root@web01 cs]# rsync -avz [email protected]:/etc ./
etc/yum/vars/infra
sent 34,372 bytes  received 10,325,252 bytes  2,302,138.67 bytes/sec
total size is 27,224,646  speedup is 2.63
